Unlike traditional manufacturing methods that mill or cut away from a slab of metal to produce a part, additive manufacturing (also known as 3D printing) grows parts directly from a computer-designed file using layers of fine metal powder and an electron beam or laser. The resulting part can be lighter weight with less waste, manufactured in a fraction of the time it would take using traditional methods. The ability to grow parts with additive manufacturing also allows for the elimination of joints and improvement of designs by creating a single, integrated part to replace an assembly.<br><br>In Auburn, Alabama, GE Aerospace opened the aviation industry’s first site for mass-producing aircraft engine parts using additive manufacturing. Employees in Auburn began producing additive fuel nozzle tips in 2015. Today, GE Aerospace and CFM International have more than 10 additively-made parts approved by the U.S. Federal Aviation Administration (FAA) for commercial aviation use for GE90, CFM LEAP, GEnx and GE9X engines. Upon certification of GE’s Catalyst turboprop engine, GE Aerospace could have more FAA-certified additive parts in commercial operation, including engine structural parts. </p></div><div class="card-btn-block"><div class="ge-txt-btn text-button-light"></div></div></div></div></div> <div class="wp-block-aero-cards col-xl-4 col-lg-6 col-md-6 col-12 alignfull"><div class="card-container d-flex flex-wrap"><div class="col-12 card-image-block"><picture class="card-image d-flex"><img class="img-fluid" src="/sites/default/files/card-breakthrough-materials.jpg" alt="GE Aerospace Image"/></picture></div><div class="card-body"><div class="eyebrow d-flex"></div><div class="card-desc-block"><h4 class="card-text card-title heading-200">Breakthrough materials</h4><p class="card-text card-sub-text body-2">Since introducing carbon fiber composite fan blades to service with the GE90-94B engine in 1995, GE Aerospace has accumulated more than 25 years and over 100 million engine flight hours of experience with composite fan blades. Today, GE and CFM International remain the only aircraft engine manufacturers with composite fan blades in commercial service.<br><br>Carbon fiber composite fan blades are higher strength and lighter weight than the traditional titanium fan blades they replaced, helping improve fuel efficiency in GEnx, CFM LEAP and GE9X engines compared to their predecessors. When the GEnx entered service in 2011, carbon fiber composite materials were expanded to the fan case, as well as the fan blades, helping the GEnx reach up to 15% better fuel efficiency than the CF6 engine. <br><br>Ceramic Matrix Composites (CMCs), another type of composite material, are lighter weight than traditional material alloys and more heat resistant, allowing engines made with CMCs to operate at higher temperatures with less cooling air. The CFM LEAP engine, which entered service in 2016, was the first to contain a CMC part in the engine’s hot section and is 15% more fuel efficient than the CFM56 engine. <br><br>GE Aerospace continues to advance carbon fiber composite and CMC materials for next-generation aircraft engines, including looking at expanding composite materials to more areas of an engine. </p></div><div class="card-btn-block"><div class="ge-txt-btn text-button-light"></div></div></div></div></div> <div class="wp-block-aero-cards col-xl-4 col-lg-6 col-md-6 col-12 alignfull"><div class="card-container d-flex flex-wrap"><div class="col-12 card-image-block"><picture class="card-image d-flex"><img class="img-fluid" src="/sites/default/files/card-advanced-aerodynamics.jpg" alt="GE Aerospace Image"/></picture></div><div class="card-body"><div class="eyebrow d-flex"></div><div class="card-desc-block"><h4 class="card-text card-title heading-200">Advanced aerodynamics </h4><p class="card-text card-sub-text body-2">Carbon fiber composites materials, along with 3D aerodynamic design have allowed GE Aerospace to improve the design of fan blades and reduce the number of fan blades in the front of turbofan engines. These advances and larger fan diameters allow the fan to pull in more air, increasing bypass ratio and air pressure throughout the engine, including in the engine core. More air flow and higher operating pressures help drive the rotor with less energy, improving fuel efficiency. GE Aerospace is a leader in aerodynamic technologies and high bypass engines, leading to the world’s largest and most fuel efficient certified engine in its thrust class—the GE9X. The GE9X engine has an unprecedented bypass ratio of 10:1 compared to its predecessor, the GE90, which has a bypass ratio of 9:1. </p></div><div class="card-btn-block"><div class="ge-txt-btn text-button-light"></div></div></div></div></div> <div class="wp-block-aero-cards col-xl-4 col-lg-6 col-md-6 col-12 alignfull"><div class="card-container d-flex flex-wrap"><div class="col-12 card-image-block"><picture class="card-image d-flex"><img class="img-fluid" src="/sites/default/files/2024-01/lean-burn-combustion.jpg" alt="GE Aerospace Image"/></picture></div><div class="card-body"><div class="eyebrow d-flex"></div><div class="card-desc-block"><h4 class="card-text card-title heading-200">Lean burn combustion </h4><p class="card-text card-sub-text body-2">Lean-burn combustion technologies accommodate the increased temperatures associated with higher pressure ratios while reducing emissions of nitrous oxide (NOx) by using a twin-annular pre-mixing swirler to optimize the air and fuel mixture.
